Lung cancer is a serious malignancy, and lung adenocarcinoma (LUAD) the most common pathological subtype. Immune-related factors play an important role in lymph node metastasis. In this study, we obtained gene expression profile data for LUAD normal tissues from TCGA database analyzed their immune-related genes (IRGs), observed that 459 IRGs were differentially expressed. Further analysis of correlation between expressed metastasis revealed 18 metastasis-associated IRGs. addition, mutations status, function pathway enrichment these IRGs, regulatory networks established through TF genes.

Abstract Osteosarcoma (OS) is the most prevalent and fatal type of bone tumor. It characterized by great heterogeneity genomic aberrations, mutated genes, cell types contribution, making therapy patients management particularly challenging. A unifying picture molecular mechanisms underlying disease could help to transform those challenges into opportunities. This review deeply explores occurrence in OS large-scale RNA regulatory networks, denominated “competing endogenous network” (ceRNET), wherein different biotypes, such as long non-coding RNAs, circular RNAs mRNAs can functionally interact each other competitively binding shared microRNAs. Here, we discuss how unbalancing any network component derail entire circuit, driving onset progression impacting on proliferation, migration, invasion, tumor growth metastasis, even chemotherapeutic resistance, distilled from many studies. Intriguingly, aberrant expression networks components cells be triggered also surroundings, through cytokines vesicles, with their bioactive cargo proteins highlighting relevance microenvironment. comprehensive pave way for development innovative RNA-targeted RNA-based therapies new diagnostic tools, perspective precision oncology.
